Airbag control unit with part number P04672501AD

What does the airbag control unit P04672501AD do?

In the restraint system (SRS) of Dodge, the airbag control unit P04672501AD controls the triggering of airbags and seatbelt pretensioners. It evaluates the signals from the crash sensors and decides within milliseconds in an accident; it indicates faults via the airbag warning light.

The unit monitors the system continuously during operation. After an accident it stores crash data and locks itself.

This monitoring runs in the background and is hardly noticeable in everyday use, as long as everything is in order.

Why does the control unit P04672501AD fail?

Stored crash data forms the start of the list of causes and counts as the most common cause, even if no airbag was triggered. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage peaks.

A normal diagnostic tool cannot erase the crash data. That is precisely why a simple reset does not help.

The other causes do not always show up on solder joints and plug connections from the outside, which is why a look inside the unit alone is not enough.

How can you tell that the P04672501AD is defective?

A defect shows up as an airbag warning light in the instrument cluster that lights up permanently or intermittently. Error messages, a missing connection between the diagnostic tool and the control unit, or a fault memory that cannot be cleared also point to a defect.

• The airbag warning light lights up permanently.
• The airbag warning light lights up or flashes intermittently.
• An error message appears in the instrument cluster.
• The diagnostic tool does not find the control unit.
• The fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. The warning light is therefore a clear signal that you should have checked promptly.

Compare the part number on the label with this page. This only shows that you have the correct unit in front of you. Also have the fault memory read out, because the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 4672602AB, 4896616AA, 4896616AB, 68148034AA, P04672603AE, P04896621AE.

How does the repair of the P04672501AD work?

First have the fault memory read out and enclose the log, then disconnect the battery and remove the control unit P04672501AD. Afterwards create a repair order online and send the unit in well packed. At Airbag24, testing, repair and checking take 3–4 working days as a rule.

The order of the steps is fixed. The battery is disconnected before removal, not after it.

Airbag24 checks the unit on the test bench, replaces defective components, erases stored crash data and carries out a function test. Your own unit is then returned to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
